+# `sdk-test-procedure-concurrency` *Rust* test
+
+This module isolates procedure concurrency behavior that currently only has
+Rust module coverage.
+
+It is separate from [`sdk-test-procedure`](../sdk-test-procedure) so the shared
+procedure test suite can continue targeting other module languages without also
+requiring `ctx.sleep_until` support.
